Publication Restricted Assessment of the Correlation Between Weight Status and the Frequency of Dietician Interviews in Sleeve Gastrectomy Patients(Springer, 2021) BATAR, NAZLI; SEVDİN, SEZEN; Güçlü, Duygu; KERMEN, SEDAPurpose The aim of this study was to evaluate the relationship between the weight status of sleeve gastrectomy patients during the first two postoperative years and the frequency of dietician interviews. Materials and Methods This was a retrospective cross-sectional study, and the subjects were patients who had surgery at a special obesity clinic, Bariatriklab, in Istanbul, Turkey, between February 01, 2014, and February 01, 2018.The mean age +/- standard deviation of the participants was 38.8 +/- 11.9 years. The mean body mass index (BMI) +/- standard deviation was 44.2 +/- 6.1 kg/m(2)preoperatively. The preoperative (pre-op) and 12-, 18-, and 24-month postoperative (post-op) weights and the frequency of interviews with dieticians for 2 years after the operation were collected, and statistical analysis was performed using SPSS ver. 23.0. Results A total of 247 laparoscopic sleeve gastrectomy (LSG) patients, 161 women (65.2%) and 86 men (34.8%), were evaluated in this study. As the frequency of dietician interviews increased in the first year, the amount of excess weight loss (EWL) increased in the second year (p < 0.01). In addition, as the frequency of dietician interviews increased in the second year, the amount of EWL in the second year decreased (p < 0.01). The frequency of dietician counseling among participants who did not experience weight loss between 12 and 24 months was significantly higher than that among those who experienced weight loss (p < 0.05). Conclusion It should not be forgotten that bariatric surgery requires teamwork, and patients should be cared for with an interdisciplinary approach. Dieticians play an important role in changing nutritional habits and making them sustainable.Publication Open Access Evaluation of the Amount and Type of Beverages Consumed by University Students(Balıkesir Üniversitesi, 2021) BATAR, NAZLI; ÖZUĞURLU, İREM BERFE; KOÇAK, BETÜL; Hamurcu, Pınar; SEVDİN, SEZENObjective: This study aims to evaluate the effect of beverage consumption amount and type on body composition of the university students. Materials and Methods: A questionnaire form that contains beverage consumption questions was applied to 201 students studying at the Department of Nutrition and Dietetics, Faculty of Health Sciences, Istanbul Kültür University. The research data were evaluated using the SPSS 25th version program. Results: Of students participated in this study, 91.5% were female and 8.5% male. All 201 students who participated in this study were the students of Nutrition and Dietetics Department. The average age of these students was 20.5±2.1 years. Anthropometric measurements of the students were done, and the mean height was 166.1±7.6 cm, body weight was 59.7±11.3 kg, BMI was 21.54±3.1 kg / m², and hip circumference was 93.6±8.9 cm. In the study, significant relationship was found between BMI and beer types (p=0.028), wine (p=0.019), hard drinks (p=0.016), mineral water and soda (p=0.030) consumption amounts. A very weak statistically significant positive correlation was found between the daily sugared tea consumption and the body weight of university students (rs=0.149; p=0.035). It was observed that there was a statistically positive and weakly significant relationship between daily energy drink consumption and the body weight (rs=0.202; p=0.004). A very weak statistically significant positive correlation was found between the daily consumption of energy drinks and the BMI value (rs=0.163; p=0.021). Conclusion: It was concluded that depending on the consumption amount and variety of the beverages, beverage consumption has a relationship with body weight and BMI.Publication Open Access Effect of Pilates Exercises on the Body Composition of Fasting Females(Bezmialem Vakif University, 2022) BATAR, NAZLI; Ersin, Aybüke; Güçlü, Duygu; SEVDİN, SEZEN; KERMEN, SEDAObjective: This study aimed to evaluate the changes in the body composition of individuals who fasted and did Pilates at least twice a week during Ramadan versus those who fasted but did no Pilates. Methods: This was an experimental study conducted on 60 healthy women who were admitted to the Noi Pilates in Istanbul Turkey, which was a private Pilates studio. The study was carried out on 60 grown-up, healthy women between 18 and 65 years of age who fasted in Ramadan 2019, some of whom did Pilates and some who did not. The women involved in the study had been doing Pilates for 6 months prior to Ramadan and did Pilates at least 3 times a week during Ramadan. Results: Significant increases were observed in body mass index (BMI), triceps skin-fold thickness (SFT), muscle mass and fat percentage in the fasting and non-pilates group (p<0.05). Our study found the change in the percentage of triceps SFT and fat in women who did Pilates to be more than those who did not. BMI, muscle mass, waist circumference and hip circumference of women who did Pilates and who did not do Pilates during Ramadan did not differ compared to the first measurements, and neither of the two methods dominated in terms of these variables. Conclusion: While a long period of fasting in Ramadan leads people to inactivity, personalized exercise and nutrition programs planned by experts may result in weight loss, especially for obese and slightly overweight people.Publication Restricted Effect of Pilates on Body Composition and Some Biochemical Parameters of Women with Type 2 Diabetes on a Low-Carbohydrate or High-Complex-Carbohydrate Diabetic Diet(Zamensalamati Publishing Company, 2020) BATAR, NAZLI; Ersin, Aybüke; San, Sevil; Erdem, Mustafa Genco; Demir, Halime Pulat; Güçlü, Duygu; SEVDİN, SEZEN; KERMEN, SEDABackground: The prevalence of type 2 diabetes mellitus (T2DM) has increased dramatically in the past 30 years. The World Health Organization has prepared an action plan to stop the increase in diabetes and obesity by 2025. Objectives: This study was conducted to assess the effect of pilates on body composition and some biochemical parameters in women with T2DM on a high-complex-carbohydrate diabetic diet or a low-carbohydrate/high-monounsaturated fatty acids (MUFA) diet. Methods: This experimental study was conducted on 120 woman patients with T2DM, referring to the Fatih Medical Park Hospital's Internal Medicine Department, Istanbul, Turkey, between December 2018 and June 2019. Participants were divided into 4 groups and were followed up for 12 weeks. The mean participants' age was 41.67 +/- 3.83 years. The first group received a low-carbohydrate and high MUFA (LC, MUFA) diet, the second group received a low-carbohydrate and a high-MUFA diet and did pilates (LC, MUFA + PL), the third group received a higher complex carbohydrate (HCC) diet, and the fourth group took the HCC diet and did pilates (HCC + PL). Results: According to the applied intervention method, there were significant differences between the preliminary and final measurements of bodymass index, body fat percentage, muscle mass, and fasting blood glucose, insulin, HbA1c, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglyceride (TG) values (P < 0.05). In this study, only an increase in body muscle composition of the women in the LC, MUFA + PL group was found significant (P < 0.05). The highest decrease in body fat ratio was determined again in the LC, MUFA + PL group (P < 0.05). HDLlevels of the women who did pilates increased significantly than other groups (P < 0.05). Conclusions: In the treatment of diabetes, the patient should be evaluated with a multidisciplinary team. Diet and exercise are important non-pharmacological interventions in the treatment of diabetes.Publication Metadata only High hydrostatic pressure induced changes on palm stearin emulsions(Elsevier Sci Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, Oxon, England, 2018-07) Özel, Barış; Yücel, Umut; Öztop, Mecit Halil; SEVDİN, SEZEN; 163554; 202979Emulsions are thermodynamically unstable systems formed through blending of two immiscible fluids. Recent studies have shown that High Hydrostatic Pressure (HHP) can initiate or accelerate lipid crystallization in emulsions. In this study, the effect of HHP on lipid crystallization was examined. Emulsion samples were prepared with palm stearin (PS) as the oil phase and sodium caseinate (SC) as the emulsifier and they were pressurized at 100 and 500 MPa at 10, 20 and 40 degrees C for 15 min. In order to determine the crystal structure of the emulsions, differential scanning calorimeter (DSC) was used and the change in the crystal morphology during 28 day-storage at 4 degrees C was observed. Nuclear Magnetic Resonance Relaxometry (NMR) experiments were also conducted and transverse relaxation time (T-2) and self-diffusion coefficient (SDC) values showed a trend to follow polymorphic changes of lipid crystals. Results showed that pressure and storage time both had significant effects (p < 0.05) on the crystal structures of emulsions. (C) 2017 Elsevier Ltd.

We enrolled patients who had obesity surgery in a private clinic in Istanbul, Turkey, between February 1, 2014, and February 1, 2018. Pre-operative (pre-op) and 12th, 18th, and 24th month post-operative (post-op) weight, nutritional consumption, and CRP levels of the participants were evaluated. The DII scores of the individuals were calculated from the obtained dietary data.Results: In this study, a total of 140 SG patients, 100 women and 40 men, were evaluated. It was found that there was a positive and significant correlation between the decreasing body mass index (BMI) value and CRP value of the individuals. It was concluded that for all measurements of BMI, excessive weight loss, DII, and CRP, at least one measurement significantly differentiated from the other measurements. Post-op 18th month DII was significantly higher than the post-op 24th month DII value.Conclusions: Long-term follow-up of patients by a multidisciplinary team in the pre-op and post-op periods is required to ensure success in bariatric surgery results. Dieticians play an important role in changing and sustaining eating habits.Publication Restricted Assessment of the Quality and Reliability of Information on Nutrition After Bariatric Surgery on YouTube(Springer, 2020) BATAR, NAZLI; Yıldız, Nida; Güçlü, Duygu; SEVDİN, SEZEN; KERMEN, SEDABackground YouTube (TM) is a platform that many people, including patients, use to access health information. Recent studies have revealed that videos on YouTube (TM) are misleading or that medical videos may not contain appropriate information. This study aimed to assess the quality and reliability of videos on nutrition after bariatric surgery. Materials and Methods The keywords "after bariatric surgery diet" and "weight loss surgery postop diet" were used, and the first 100 videos for each keyword on YouTube (TM) were analyzed by considering the source, duration, content, and the number of likes of the video. The popularity of the video was calculated using the video power index (VPI) and view rate. The educational quality of the videos was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) score, the Global Quality Score (GQS), the usefulness score, and a novel postoperation nutrition score (PONS). Results One hundred fourteen patients were included in the study. The mean duration and number of views were 12.51 min and 87,558.46, respectively. The DISCERN score, JAMA score, GQS, and usefulness score of the physicians or dietician-based videos were significantly higher than those of the patient-based videos (p < 0.001). Positive correlations were found between the VPI and view ratio, as well as between the duration and number of likes. Additionally, the DISCERN score was significant correlated with the duration and number of likes. Significantly positive correlations were found between the usefulness score and duration, usefulness score and number of likes, and PONS and duration (p < 0.01). Conclusions Informational videos on nutrition after bariatric surgery on YouTube (TM) are of low quality. Although the videos uploaded by physicians and dieticians have higher quality, only a few are available. Additionally, patients prefer to watch low-quality videos.
